MuleSoft Integration professional developer for Mule 4

Is there an Integration professional exam for Mule 4 . If not is there a plan to introduce one in the future. I have completed MCD 4 level 1 exam . What should be my next course of learning . Does the API implentation certification is different from the developer one or just the architect exam would be sufficent ?
